Montelbaanstoren is a tower on the banks of the Oudeschans canal in Amsterdam. The original tower was built in 1516 as part of the city's defensive walls. In 1606, the upper part of the building was extended to its present form according to the design of Hendrick de Keyser. Since then, the tower measures 48 m in height.In 1644, Rembrandt placed it on one of his paintings (view before expansion), which made her one of the painters' favorite motifs. In 1852, it was planned to demolish the building, and in 1878 water management offices were located in its center. In 2006, the water management was moved to the new building, and the tower was completely restored.
